Best Answer: I'd say about 10-15 mins walking at a relatively average pace!! Fastest time to run a mile is around 4 minutes. The average time to walk a mile is 12 minutes, so half a mile would be 6 minutes. i walk a mile every morning in 15-20 minutes, so probably 10 minutes. At a semi rapid rate about 7 1/2 minutes.
Causes of Nose Burning Sensation: The following medical conditions are some of the possible causes of Nose Burning Sensation. There are likely to be other possible causes, so ask your doctor about your symptoms. Sunburn. Allergy to cream/lotion.
If there is strong evidence of nasal allergies or sinus congestion, they will probably want to begin with treatment of those and see if the problem with the burning smell improves. They can also evaluate you for evidence of rarer, but more serious, causes of strange smells, such as a seizure disorder or a tumor.
